PULL-STRAPv FIXTURE.

Application filed May 18,

To all whom it may concern:

Be is known that I, PAUL RISSMANN, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Pull-Strap Fixe tures,of which the following is a specificati on.

This invention relates to attaching fixtures for securing a pull strapto a window sash. I In automobile closed body construction the so-calledpull strap is still used on some windows. This strap is now usually madeup of a center of burlap strips and has a backing of waterproof fabricand a face that is usually trimmed in the same goods with which the caris trimmed. It is customary ordinarily to attach these straps to themetal channel bar that forms the lower support of the sash by means of aloop. A metal loop is usually provided on the side of the channel barand the pull strap is looped through this and then stitched to form aloop. The trouble With this construction is that it frequently tears outbecause the stitching or material is not strong enough to stand the verysevere tension that is often put on the strap especially if the windowsticks.

It is the object of the present invention to provide an attachment whichcomprises a strap fixture which may be quickly attached to the ends ofthe strap and which may be detachably engaged with a special fixturesecured on the bottom of the sash bar.

In the drawings,-

Fig. 1 shows the usual interior construction of a closed body indicatingthe pull strap.

Fig. 2 shows how the pull strap is fastened to the bottom of the sash.This is simply a fragmentary view of the bottom of the window.

a designates the ordinarypull strap which is adapted to raise and lowerthe Window 7). These windows are now made with no sash bar at thetop'and frequently none at the side. However, they have a channel bar 0Specification of Letters'Patent. Patented Aug, 15, 1922 1921. Serial No.470,648. I

the glass rests. Atthe bottom of this channel bar is spot-welded orriveted a sash fixture d which comprises simply a strip of metal stampedout as shown in Fig. 5, form-.. mg a loop e having a pair of ears fpf extending forward.

The strap fixture comprises an angle plate or stamping go {One web 1 ofthis angle plate is, provided with extending ends it. The. other web 8is provided with struck- 1n prongs 7'. The clamping plate is is adaptedto match the web 8 of the angle plate and at the bottom'in whichthelower edge of I is provided witha plurality of struck-in v projections Zat the endof which are;slo ts m. able dies to hold the angle plate 9 andthe clamping platelc. The end of the strap can be interposed between thetwo plates and the prongs j can be driven through the strap ,70 Amachine can be provided with suitend and through the slots m of theplate k. i

The prongs are then turned over by the press I into the depressions Zwhich are just the shape to nicely receive them. This avoids theirprojecting to any extent above the surface of the plate k and makes aneat, clean job of it.

When this has been done the fixture is neatly attached to the pull strapwith the end extensions extending to the sides of the strap. The strapmay then be inverted, as shown in Fig. 2, the back of the strap facingthe observer. The web 1- with the end extensions h is then slipped intothe loop 6. The ears 7 are then simply bent up beyond the end extensionsh, locking the fixture into the sash fixture.

These two fixtures not only form a attachment for the pull strap to thewindow sash but the strap fixture forms a very neat salvage for the endof the strap. The strap fixture may be applied by a suitable set of diesand a small press very rapidly so that strong the article is a largeproduction proposition.
